Enabling fast-leave processing
About fast-leave processing
This feature enables an IGMP querier to send leave notifications to the upstream without sending group-specific or group-and-source-specific queries after receiving a leave message. Use this feature to reduce leave latency and to preserve the network bandwidth.
Restrictions and guidelines
The fast-leave processing configuration takes effect only when the device runs IGMPv2 or IGMPv3.
